This paper presents a technique to control blower for the residential applications at constant air flow rate using induction motor drive. The control scheme combines a variable VoWHertz ratio inverter drive and an average motor current regulation loop to achieve the control of the motor torque-speed characteristics, and consequently controlling the air flow rate of the blower which the motor is driving. The controller is simple for implementation and practical for commercialization, it is also
